KCore practical-skills safety note: Reading or passing this quiz does not create practical diving competence. Essential skills must be learned and repeated in controlled water with appropriate supervision until they can be performed reliably while breathing continuously and maintaining buoyancy, trim and awareness. Procedures vary by training system, environment and equipment.
